IQC5000B Series RF Signal Record and Playback Value of RF Streaming - PowerPoint PPT Presentation

IQC5000B Series RF Signal Record and Playback

Value of RF Streaming • Evidence of what happened – Designers are not always sure what they’re looking for: • “good” signals well understood • “bad” signals can exist in many forms – 100% capture allows engineers to discover anomalies • Characterize precise behavior in multiple domains • Terabyte memories provide capture times from minutes to days – RF streaming creates signal archives • Compare to previous events • Manipulate and re-transmit signals Cannot Always Model or Capture Anomalies in the Lab 2 3/5/2015

The Measurement Problem • It is often difficult to detect or predict the occurrence of signals of interest – Stray emissions from a known device – Unauthorized emissions – Unpredictable interactions in complex RF environments Lockheed Martin F-35 Joint Strike Fighter • Streamed signals are information – Undeniable proof of what happened – Use data to find other data – Modify and replay recordings to stress and margin test receivers 3 3/5/2015 Asymmetric Threats

IQC5000B Applications: Co-Channel Recording • Threat-response characterizations – When did the threat appear? – How long did it take to respond to the threat? – What impact did interference have on response times? • EMI/TEMPEST testing – What emissions exceeded design thresholds? – Were there any transient emissions? • MIMO systems – Timing correct between the 2 receive paths? – Did environment impact each receive path? – Interference present when 2 channels recorded? 8 3/5/2015

IQC5000B Applications: Multiband Recording • Satellite uplink/downlink – On which link did the interference occur? – When did the interference occur? – What was the impact on signal quality? • Cellular forward and reverse links – Did the base station generate stray emissions when it changed modes? – Why are calls being dropped during rush hour? • Spectrum studies – Record contiguous blocks of spectrum – Document spectrum usage next to assigned channels 9 3/5/2015

IQC5000B Applications : Geospatial Studies • Simultaneously record RF and GPS – 100% capture of real-world environment for minutes and hours Channel 1 • Recreate the environment back in the lab – Where was I when the emitter was first detected? – How long did the emitter stay on? – Were there other signals of interest in the Channel 2 vicinity of the first? – What signals require detailed signal analysis? 10 3/5/2015
